Abstract
Električni tramvaj je gradsko prijevozno sredstvo koje je zastupljeno u većini Europskih gradova. Konkretno u Zagrebu predstavljaju neizbježan oblik prijevoznog sredstva. Često se nalazi u interakciji s pješacima i drugim oblicima gradskog prijevoza te se zato nerijetko stvaraju kritične situacije. U ovome završnom radu proučavalo se gibanje tramvaja prilikom pojave kritične situacije. Prvo se morao odrediti dinamiˇcki model tramvaj korištenjem sila. Napravljena se dva dinamička modela, jedan za gibanje tramvaja na ravnoj pruzi te drugi za gibanje tramvaja u zavoju. U teoriji tramvaj može imati veliku akceleraciju, no ona mora biti ograničena zbog osiguravanja sigurnosti i udobnosti putnika. Ako bi iznos akceleracije bio prevelik mogao bi uzrokovati gubitak ravnoteže te posljedično pad i ozlijede putnika. U ovome radu navedene su vrijednosti graničnih i akceleracija i njenih promjena raznih istraživanja pri kojim putnici počinju osjećati gubitak ravnoteže ili neudobnost. Osim toga navedeni su uzroci koji dovode do kritične situacije te ograničenja koja se moraju uzeti u obzir prilikom stvaranja reference kočenja u kritičnoj situaciji. Zatim je napravljen model tramvaja prema aproksimativnim vrijednostima na kojima su se testirale napravljene reference kočenja. Model tramvaja, motora i referenci kočenja napravljeni su u MATLABU korištenjem Simulinka.
Abstract (english)
Electric tram is an urban transportation system which is highly represented in most cities on the European continent. Specifically in Zagreb it is an inevitable trasportation method. It is often in interaction with pedestrians and other forms of urban transport and because of it critical situations appear. In this paper the motion of the tram during critical situations was studied. In the beginning the dynamic model of the tram using forces had to be conducted. Two dynamic models were created, first one for the motion of the tram on a tangent track and second for the motion on a curved track. In theory tram can create a large value of acceleration but it has to be limited because of securing safety and stability of passengers. If the accleration is too big it could cause loss of balance and consequently passenger injuries. In this paper the limits of acceleration and jerk on which passengers start to lose balance and feel discomfort from different papers are listed. Besides that the causes of critical situations are listed as well as limitations that have to be used when creating a braking reference for a critcal situation. In the end a model of the tram was created using approximative values on which the braking references were tested. The model of tram, motor and braking reference were made in MATLAB using Simulink.
